Description

In the present invention, after cutting the roll paper with a paper cutting blade provided on the front edge of the cover body, the roll paper automatically circulates in the front direction by a certain amount, and the front surface of the cover body is used as a picking allowance for the next use. It relates to a roll paper holder in which a paper having a certain length is fed out from the edge and hangs down.

The roll paper holder includes a shaft in which a serrated gear part is formed so as to be able to rotate with the roll paper, and a gear of the shaft that is swayably attached by hanging from the cover and only when the cover is separated from the shaft. A toothed member that meshes with the portion and a peeling member that temporarily floats the outermost peripheral portion of the roll paper immediately before the roll paper is unwound are provided, and the roll paper can be rotated by a predetermined angle by pushing down and releasing the cover, and can be unwound. After pulling out the length of the cover, the cover is pushed down to cut the roll paper, and when the hand is released from the cover, the optimum length for the next use is pulled out (for example, Patent Document 1). reference).
The roll paper holder disclosed in Patent Document 1 has a problem that the hand touches the cover and bacteria such as Escherichia coli and manure adhering to the fingers may adhere to the cover, which is unsanitary.
A roll paper holder is disclosed in which the roll body is rotated by a means for rotationally driving the core member by restoring the cover body position after the cover body is pushed down to the position of the cover body before the cover body is pushed down, and the tip of the roll paper is hung down (for example, a patent). Reference 2).
With the roll paper holder disclosed in Patent Document 2, since the cover body is pushed down by hand, germs such as Escherichia coli and manure adhering to the fingers may adhere to the cover body, and the sanitary state of the cover body is not maintained. There was a problem.
The hook part and the pin can be engaged and disengaged between the rotation support arm having a pin at the top and having a detent side of the blade part that can rotate along the arcuate groove and the crank having a hook part at the tip. It has an automatic sliding protrusion retracting mechanism provided, a blade with a claw at the tip of the back surface, a protrusion at the center of the front surface, and a blade with a stopper side at the tip of the back surface, and holds the roll paper in a case that moves up and down inside the holder body. Then, the pulled-out tip edge of the roll paper erected at the side edge of the holder body and the edge of the case is sandwiched, and the paper edge is pulled toward you to rotate the roll paper and the paper is appropriately rotated. When the amount is fed out, the cutter is projected from the side edge of the holder body, the paper pulled by the protrusion of the cutter blade is cut, the protrusion and the side edge are removed, and the blade is the side edge of the holder body. A roll paper holder has been proposed in which the paper is pulled into a portion and the end portion of the paper is left outside the side edge portion of the holder body so as to be used as a picking allowance for the next use (see, for example, Patent Document 3). ..
The one-handed roll paper holder disclosed in Patent Document 3 has a configuration in which when the paper is no longer pulled, the locked state due to the protrusion and the side edge portion is released, and the blade portion is pulled from the side edge portion by the restoring force of the spring. Yes, it is different from the configuration of the present invention.
The push-in rotation plate and the follow-up paper cutting plate are overlapped and attached as a cover body, and the roll paper is drawn out toward you with the push-in rotation plate and the fan-shaped tooth profile plate pressed by hand, and the tip is cut off by the follow-up paper cut plate. After that, it is disclosed that the work of releasing the hand from the push-in rotating plate is performed again after use to expose a desired amount of paper from the front edge of the cover body toward the front (see, for example, Patent Document 4).
The rolling paper holding device disclosed in Patent Document 4 is troublesome because the paper cannot be cut unless the push-in rotating plate and the fan-shaped tooth profile plate are pressed by hand, and it is particularly troublesome for a woman who has decorated her nails. There was a problem that the nails might hurt. Also, for the convenience of the next use, the paper for picking does not come out automatically after use, but the paper is pulled out toward you while pressing the push-in rotation plate and the fan-shaped tooth profile plate by hand. There is a problem that it is necessary to perform artificial work, and bacteria such as Escherichia coli and manure adhering to human hands after defecation may adhere to the push-in rotation plate and the fan-shaped tooth profile plate, and the hygienic condition of the cover body is not maintained. There was a point.
Further, all of the inventions disclosed in Patent Documents 1 to 4 have a problem that cutting is difficult because the roll paper rotates when the paper is cut.
In view of the problems of the above-mentioned conventional example, the inventor of the present application cuts the roll paper with the cutting blade of the front edge of the cover body and automatically rotates the roll paper toward the front at the same time as cutting the roll paper from the front edge of the cover body.
